CL. The CL has nice performance for teeth10. For blocks and mix, its performance is satisfactory though not belonging to the first class. For both of the fms signals, it shows rather average performance. The CL does not behave well for the stairs10 signal where it tends to overestimate the number of changes compared to other methods. Let us remark here that the performance of CL in our simulation study is better than the corresponding context in [1]}. This is because when implementing the package Segmentor3IsBack, users need to set the maximum number of segments \(N_{\max }\) . We set \(N_{\max }=20\)  for all the six signals considering the maximal number of changepoints (i.e. \(N-1\) ) among six signals is 14 and they set \(N_{\max }=15\)  which resulted in a systematical underestimation of the number of changepoints for CL in their study.
